Öhlins machines its pistons rather than sintering them, which is why the port edges stay sharp.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eThread M12x1.25\u003c\/li\u003e\n\u003cli\u003eDimension B 49 mm\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eDimension A 8 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 03172-02\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat It Is\u003c\/h2\u003e\u003cp\u003eAt 8 mm, 49 mm it fits one position only; the next size up carries a different number. Twin-tube pistons have separate paths for compression and rebound, which is the whole point of the design. Öhlins uses a piston band rather than metal-to-metal contact, which is what keeps the bore intact. Rebuilding a piston means keeping the shim order, because the stack is the tuning.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eThe alternative to a service part is usually a new damper, which is why this catalogue exists. Öhlins supports its suspension with individual service parts, which is why a fifteen-year-old damper can still be rebuilt to specification. Service parts are ordered per piece unless stated otherwise. Tell us the damper's model designation and year and we will match the number for you.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eThe reliable route is the exploded drawing: find the position, read the number, order it — 03172-02 in this case. dimension a 8 mm, dimension b 49 mm is what distinguishes this number from its neighbours in the range. Port area and shim seat geometry decide the damping curve before any adjuster is touched. Needle geometry sets the shape of the adjustable range, not just its size.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eWe are an authorised Öhlins service centre, so you do not have to source the tools and the nitrogen: send us the damper and we rebuild it with the correct parts and the correct setting.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eBrand:\u003c\/em\u003e Öhlins\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003ePart Number:\u003c\/em\u003e 03172-02\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Piston Holders\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 8 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 49 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThread:\u003c\/em\u003e M12x1.25\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCountry of Origin:\u003c\/em\u003e Sweden\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Öhlins","offers":[{"title":"Default Title","offer_id":53648846029066,"sku":"03172-02","price":353.16,"currency_code":"SEK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/03172-02_140ebd30-beff-4997-85d5-082eb4139d09.png?v=1788872174","url":"https:\/\/inter-pace.com\/en-se\/products\/ohlins-piston-holder-8-49-m12x1-25-03172-02","provider":"Inter-Pace","version":"1.0","type":"link"}
